Problem Description

Since BF was updated to use ANTLR 4.11.1 (in 4.2.0) it is no longer possible to use new AdaptiveCardTemplate(json) in the same project

It fails with this error:

      System.TypeInitializationException: The type initializer for 'AdaptiveCardsTemplateLexer' threw an exception.
       ---> System.MissingMethodException: Method not found: 'Antlr4.Runtime.Atn.ATN Antlr4.Runtime.Atn.ATNDeserializer.Deserialize(Char[])'.
         at AdaptiveCardsTemplateLexer..cctor()
         --- End of inner exception stack trace ---
         at AdaptiveCardsTemplateLexer..ctor(ICharStream input)
         at AdaptiveCards.Templating.AdaptiveCardTemplate..ctor(Object jsonTemplate)

Card JSON

Example, but all fail:

    "type": "AdaptiveCard",
    "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
    "version": "1.5",
    "body": [
        {
            "type": "TextBlock",
            "text": "this doesnt work",
            "wrap": true
        }
    ]
}

I have created a repro below:

If you dotnet run, you will see:

❯ dotnet run
